DETERMINATION OF MIXTURES OF DIETHYLENE TRIAMINE WITH HYDRAZINE AND SUBSTITUTED HYDRAZINES
Abstract
A method is presented for determining admixtures of diethylene triamine-hydrazine, diethylene triamine-monomethylhydrazine, and diethylene triamine-1, 1-dimethylhydrazine in a non-aqueous titration system using methanol as a solvent, hydrochloric acid in methanol as the titrant, and bromocresol green as indicator. The method uses the reactions of salicylaldehyde which forms the neutral azine with hydrazine, the neutral hydrazones with monomethylhydrazine and 1, 1-dimethylhydrazine, and a basic Schiff base with diethylene triamine. The total basicity of the admixtures is determined on separate aliquots of the mixtures before and after the addition of salicylaldehyde. This procedure lends itself readily for quality control by untrained personnel with a minimum of equipment. (Author)
